See below for answers and explanations (with attached graph)
Step-by-step explanation:
It helps to transform the equation into vertex form by completing the square because it tells us a lot about the characteristics of the parabola:

Since vertex form is
, we identify the vertex to be
and the axis of symmetry to be
. The y-intercept can be found by setting
and evaluating:

Hence, the y-intercept of the parabola is
, or
as an ordered pair.
Answer:
It had flown 2620 ft along the diagonal.
Step-by-step explanation:
When the plane is taking off it forms we can form a triangle with it's height, horizontal distance and diagonal distance, which can be seen in the attached drawing. We can use the sine relation on the right triangle to determine "x", as shown below:
sin(11°) = 500/x
x*sin(11) = 500
x = 500/[sin(11)] = 2620 ft
It had flown 2620 ft along the diagonal.
Answer:
$20
Step-by-step explanation:
<em>20% is equal to 20/100 therefore, if 5 x 20 is 100, you would multiply 5 x 4 and get 20, </em>
the reason you don't subtract the $4 is because it says "was" so the answer is $20
